Watt Stopper Dual technology low voltage wall switch occupancy sensor in white color operates at a voltage rating of 18 - 24 VDC/24 VAC. Sensor current consumption is rated at 35 milli-Amps. It uses PIR with ultrasonic technology that turns light ON/OFF. It accommodates detection signal processing that offers immunity and eliminates false trigger. It has vandal resistant lens that offers durability and has zero crossing for longer relay life. It has walk-through mode that turns OFF light after 30 seconds, if no motion is detected or in three minutes after the room is occupied. Switch occupancy sensor provides choice of manual-ON or auto-ON.

The DW-100 dual technology wall switch sensor combines the benefits of passive infrared (PIR ) and ultrasonic technologies, and can turn lights OFF and ON based on occupancy. It is characterized by high sensitivity to small and large movements, appealing aesthetics, and a variety of features.
